KEO Countersink: 60°, 1 Flute, 1/2 in Body Dia

The KEO 60° countersink is used to create a conical recess for flathead screws or deburr holes in metal, plastic, and wood. Its single-flute design provides fast, chatter-free cutting in production and maintenance applications. Ideal for aerospace, automotive, and general fabrication where precise 60° chamfers are required.

The KEO 919-000-557 is a 60° single-flute countersink with a 1/2 in body diameter, made from cobalt steel for heat resistance and durability. It is designed for fast cutting and produces a smooth finish. The cobalt material extends tool life when machining harder materials like stainless steel.

Select the KEO countersink based on the required chamfer angle (60° for standard flathead screws), body diameter matching the screw head size, and material compatibility. Cobalt steel is best for hard metals; high-speed steel suits softer materials. Single-flute designs reduce vibration for cleaner cuts in production runs.
